Issues when updating the RRC's Firmware using USB

[Jan (Microbit)]

A quick update about this:

We have now a PC here at Microbit which fails updating firmware via USB(write failed). We will start looking deeper into it next week, and hopefully we will at last find a remedy for this issue.

My RRC-Radio (RRC-1258 MK2) failed to renew new firmware.

My RRC-1258MK2 + IC-706 are working well on my LAN.

Recently, I am going to renew the firmware versions.

At first RRC-Control was renewed firmware RRC-1258-CRC_v2.30
to RRC-1258-CRC_v2.35 successfully via USB.

However, my RRC-Radio was never renewed.

Microbit Setup Manager saied
[Failed programming new firmware: Write failed!]

I tried many times, always failed.

[FW/HW version],[Setup],[Net info] are working well.

I tried [Application upgrade] via the browser and got success.

What is wrong on updating via USB connection ?

Please read the posts of this thread and you will see that we are investigating this problem right now.

This might sound crazy, but try unplugging all external USB devices from your computer.  With just the RRC plugged into the USB port, try to program the RRC.  Maybe the RRC needs all the current the USB port can provide?

If it works when doing that it must be something else than the RRC's need for current, since it is a self powered device it needs very little current. Also the PC we now have gets that error with only the RRC connected to it. I have not had the time to start look deeper into it yet, but it looks like the RRC is resetting itself and therefore the PC gets "write failed". I suspect the PC does something too fast for the RRC to handle.

Good news ppl!

We have now been able to hunt down what is causing the "Write failed" when updating firmware via USB on some computers! We are hopeful it will fix that problem on all the computers suffering from it. It will require a new firmware (2.36) in the RRC. It was a timing issue which only showed up on certain computers which somehow has a faster USB handling than others. Obviously you who have this problem will first have to update using the web page, but after that it should work via USB too.

This feels really good since this issue has been haunting us a long time, as well as affecting some of you!

Since I am just setting up my new RRC 1258 units and it seems the USB issue is not yet resolved, should I just use the version 2.33 shown in my units and proceed with set-up? I could update firmware later,I assume.

The USB-problem is solved. If you suffer from it update to v2.36 via the web interface, then it works even from USB next time.

I upgraded from 2.33 to 2.39 via web server with no problems. USB upgrade failed before but hopefully we have web option upgrade. My bootloader is 1.8
